Thin lips occur when the natural volume and definition of the lips are minimal, asymmetrical, or lacking fullness. Some individuals are born with naturally thinner lips, while others experience volume loss due to aging, which can cause the lips to appear flatter or less defined over time. As collagen production declines, lips may become less plump and develop fine lines around the mouth. Whether you want to restore youthful fullness or enhance your natural shape, professional treatments can create balanced, proportionate lips that complement your facial features.
